CAR-COUPLING.

Speccation of Letters Patent. Patented Feb. 26, 1918.

Application filed October 15, 1917. Serial No. 196,681.

To all wia/0m t may concern.'

Be it known that l, ADAM Macironosnr, a citizen of the United States of America, residing at Kewanee, in the county of l-ienry and State of Illinois, have invented certain new and useful Improvements in Car-Gou-V plings, of which the following is a specification.

This invention relates to certain new and useful improvements in car couplers.

The primary object of the invention is to provide a coupler for cars that is easy and cheap to manufacture but at the same time possesses great strength and is formed so as to consume an exceedingly small amount of space upon the cars.

A further object is to provide a coupler for cars pivoted for operation within cutaway portions of the end platforms of the car and furnished in pairs, one being carried at each end of each car, each pair being operable when adjacent cars are coupled together for releasing from opposite sides of the train. Y

A still further object is to provide a pivoted coupler and a keeper ateach end of cars and means upon. each car for releasing the engaged couplers when the adjacent cars are secured together thereby.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts to be hereinafter more fully described, illustrated in the accompanying drawings, and set forth inthe appended claim.

ln the drawings forming a part of this application and in which likeedesignating characters refer to corresponding parts throughout the several views- Figure 1 is a side elevation of portions of two cars provided with the present invention coupling the cars together, a portion of one platform being shown broken away, and one of the vcouplers with its operating cam shown in dotted lines in its releasing position.

Fig. 2 is a top plan view thereof.

Fig. 3 is an end elevation of the car provided with the device.

Fig. 4c is a vertical transverse sectional. view taken upon line lV-lV of Fig. 2, and

Fig. 5 isa perspective view of the coupler operating means detached.

Referring more in detail to the drawings,

the portions of two cars l() and 11 are disclosed in the drawing provided with end platforms 12 and 13 respectively each provided with an identical lform of coupling means. A coupler 11i; is pivoted by means of its cylindrical head 15 within a 'vertical opening 16 of each end platform of each car, the same being mounted upon a pivot bar 1T traversing the said opening 16 and journaled in a bushing 1S carried by the platform. lt will be noted from an inspection of Fig. 2 that the cylindrical head 15 is wider than the shank of the coupler 1+i and that the vertical opening 16 .is wider lthan the slot which receives the shank. The purpose of this is to relieve the pull on the pivot bar 17 and bring a part of the stress directly on the platform. A cap 19 is provided. at the outer end of the bushing and at one side edge of the platform for closing the bushing end and retaining the rod 17 therein, -the said plate being retained by means ofk suitable screws 20. The underside of the coupler being cut-away as at 2l allows the-coupler to rest horizontally within the slot 22 of the car platform and engaging the bottom 23 ofthe said slot.

The cutting away of the lower side of the coupler provides a forwardly positioned hook 24 at the free end and upon the under side of the coupler which has its forward end 25 beveled or curved. Each platform is also provided with a keeper opening 26 ven tically positioned therethrough and having an entrance groove 27 for receiving the hooked end of the coupler when the cars and their platform are moved together, the groove having an inclined front bottom portion 28 up which the end of the coupler is adapted to ride upon its curved surface 25 until the hook 24 rides over the forward edge of the keeper opening 26 and engages the inclined keeper edge 29 of the said opening.

Each platform. is provided with a coupler releasing member formed of a shaft 30 revolubly journaled therebeneath in spaced brackets 31, the said shaft having at one of its outer ends a turning crank 31. These cranks are preferably provided at only one end of each of the shafts 30 and at opposite sides of the car upon the opposite end platforms thereof, although it is obvious that the shafts may be of sufficient length to provide an operating crank at each end thereof.

The adjacent platforms 12 and 13 being provided With similar couplers and keeper openings, it will be seen that a positioning of the cars together and with the adjacent ends of the platforms in substantial Contact with each other, the couplers will automatically become engaged with the keeper faces 20 of the keeper openings and at which time the pair of couplers will firmly lock the cars together. The bottom of the grooves 27 are provided withfnotches 32 while the bottom 23 of the coupler-receiving groove 22 are provided with similar notches 33 and whereby similar cams 34 iixed to and carried in spaced relation upon the shaft 80 are adapted to move upon operative turning of the shaft crank 31.V It will thus be seen that when the pair of couplers are in engagement as shown inFig. 2 for coupling the cars together', the two couplers may be readily opened by one of the cranks 31 which are positioned at opposite sides of the cars, aV

turning ofV either crank eiiecting an upward movement of its cams Se through the notches 32 and 33 and thus engaging the lower side ofeach ofthe pair of couplers and elevating each of the saine and disengaging the hooks 24 from the keeper faces 29.V

The sha-ft 30 is secured within the brackets 3l by means of exteriorlypositioned collars secured to the shaft. It will thus be seen that a Vcoupler is provided composed of two parts and of simple construction but which is nevertheless to be understood that minor changes may be made without deliiarting from the spirit and scope of the i1 vention as claimed.

What I claim as new is The combination with two opposed ear platforms, the first of said car platforms having pivoted thereto for vertical movement, a coupler having its free end provided With a hook, the second of said ear platforms having means to engage said hook, a shaft extending transversely of the second platform beneath the said hook7 an ovaie cam fixed at its smaller end on said shaft beneath said hookl and constituting a weight to normally hold the shaft in a iixed position and present an enlarged continueusli.v curved cam face, and a handle on said sha 't of less weight than the cam whereby the cam normally rests in depending position, said cam being arranged when the handle is manually rotated to engage the hook and disengage the latter from the hook retaining means.

In testimony whereof I aiiix my signature.

ADAM MACHOROSY.
